Mẫu Log

Một luồng dữ liệu trực tiếp gồm tối đa 20 dòng mới nhất xếp trước, mỗi dòng kèm dấu thời gian và mức độ nghiêm trọng tùy chọn. Máy chủ lưu giữ một kho lịch sử có thể cuộn lại mà bạn có thể tải về trong ứng dụng, trong khi Live Activity luôn hiển thị các dòng gần đây nhất.

Fields

Field	Type	Description
`template`	string	Required. Must be `"log"`
`lines`	array	Required. 1–20 line objects, newest first (see below)
`title`	string	Log heading shown above the feed
`state`	string	Status text shown beside the title (e.g. the source name)
`icon`	string	SF Symbol name (e.g. `"doc.text"`) or MDI icon with `mdi:` prefix
`accent_color`	string	Named color or hex used for the heading icon. Default: `blue`
`background_color`	string	Background color override
`text_color`	string	Text color override

Line object

Each entry in lines is an object:

Field	Type	Description
`text`	string	Required. The log message. Max 512 characters
`at`	integer	Unix timestamp (seconds) shown as the line's time
`level`	string	One of `info`, `warn`, `error` — tints the line and its marker

ℹ Thông tin

Send the newest line first, up to 20 lines per push. To stream a feed, prepend the new line and re-send the array. The Live Activity always shows the most recent lines that fit the ~4 KB APNs payload.

💡 Mẹo

The server keeps a rolling scroll-back backlog beyond what fits on screen. The PushWard app fetches it with GET /activities/{slug}?include=log_backlog to show full history in-app — the field is read-only and never needs to be sent.

Example: Streaming Deploy Log

Log triển khai trực tiếp

{
  "state": "ongoing",
  "content": {
    "template": "log",
    "title": "Deploy Log",
    "state": "pushward-server",
    "icon": "doc.text",
    "accent_color": "purple",
    "lines": [
      { "text": "Rollout complete — 3/3 pods healthy", "at": 1718990000, "level": "info" },
      { "text": "Image pull slow on node arm-2", "at": 1718989950, "level": "warn" },
      { "text": "Applied manifest revision d86246c", "at": 1718989930, "level": "info" },
      { "text": "Sync started by webhook", "at": 1718989900, "level": "info" }
    ]
  }
}

Typical Flow

Start the feed (ended -> ongoing): Send the first batch of lines, newest first
Append events (ongoing -> ongoing): Prepend each new line and re-send lines — older lines roll into the backlog
Finish (ongoing -> ended): Send a closing line, then end the activity

Use Cases

CI/CD — live deploy and pipeline logs
Home automation — event feeds (motion, doors, presence)
Monitoring — rolling alert and incident streams
Self-hosting — download/import progress, backup steps, sync activity
